Porphyrin-embedded materials (PEMs) combine the tunable binding selectivity, high surface area, and low materials
density of a highly ordered pore network with the unique properties of porphyrins. Porphyrins are a family of large,
nearly planar molecules which strongly absorb visible light and fluoresce intensely. They are highly sensitively to
alterations in their immediate environment making porphyrins valuable as indicators. They are well established electroand
photocatalysts and have been used in this capacity in a wide range of applications. Surfactant-templated nanoporous
organosilicas have great potential for the adsorption of small molecule contaminants. They can be synthesized with high
surface areas, uniform pore dimensions, and ordered nanostructures while incorporating organic bridging groups in the
pore walls that may be tuned for adsorption of a specific class of compounds. In the porphyrin-embedded materials, the
organosilica scaffold stabilizes the porphyrin and facilitates optimal orientation of porphyrin and target. The materials
can be stored under ambient conditions and offer exceptional shelf-life. The selectivity of the materials can be
controlled both through incorporation of varying organic bridging groups in the organosilica structure and through
selection of the porphyrin component.
